Shortly after Manziel officially announced he would enter the 2014 NFL Draft, Tarkenton took to Twitter and gave his thumbs up to the quarterback as well as the comparison. "Manziel is a football savant," he tweeted. "Can't teach what he does."

Tarkenton, for one, is hoping his former team targets Manziel in the draft.

Would love to see Johnny Manziel in a @Vikings uniform. This guy is the real deal. He will be a big time player on Sundays. #NFL@jmanziel2

Whether Manziel will still be on the board is uncertain. According to Jeremiah, four of the teams drafting ahead of Minnesota -- Houston at No. 1, Jacksonville at No. 3, Cleveland at No. 4, and Oakland at No. 5 -- have a need at quarterback. The Browns in particular are reportedly very high on Manziel.
